Learn how to set up TLS in Spring.
Secure communication plays an important role in modern applications. Communication between client and server over plain HTTP is not secure. For a production-ready application, we should enable HTTPS via the TLS (Transport Layer Security) protocol in our application. In this tutorial, we’ll discuss how to enable TLS technology in a Spring Boot application.

As an extension of the Spring Framework, Spring Boot is widely used to make development on Spring faster, more efficient and convenient. In this article, we will look at some of the parameters were using Spring Boot can drastically reduce the time and effort required in application development.

Spring Native, for compiling Spring Java applications to standalone executables called native images, is now available as a beta release. Native images promise faster startup times and lower runtime memory overhead compared to the JVM.
Launched March 11 and available on start.spring.io, the Spring Native beta compiles Spring applications to native images using the GraalVM multi-language runtime. These standalone executables offer benefits including nearly instant startup (typically fewer than 100ms), instant peak performance, and lower memory consumption, at the cost of longer build times and fewer runtime optimizations than the JVM.

The spring framework is one of the most versatile frameworks in java which is used to bring down the complexity of the development of enterprise-grade applications. The first production release of the spring framework was in March 2004 and since then, this robust and open-source framework has gained tremendous popularity, so much so that it is often referred to by developers all around the world as the “framework of frameworks”. Spring is a loosely coupled, open-source application framework of java. It is lightweight and the inversion of the control container for the Java platform. A large number of Java applications use the core features of the spring framework. In addition to that, extensions have also been developed to allow developers to develop Web Applications on top of the Java Enterprise Edition platform.

It’s impossible to write OOP code with Spring. From its core it promotes the use of singletons and anemic data structures a.k.a. data “objects” a.k.a. DTO. This fuels procedural programming and kills OOP.
In the next paragraphs I’ll highlight three **major **Spring components involved. I start from the core.
The core of Spring is the IoC container, represented by the
ApplicationContextinterface. Basically it defines a context through which we get beans. A bean is an object managed by the container and it has a name attached to it.
We can configure the context thanks to some annotations, called steorotype. These annotations were introduced in Spring 2.5 and enhanced in Spring 3.0. Previously we could only use an external XML. This was even worse…
So we annotate a class with a stereotype, the container reads it and it builds a bean. A bean is a singleton. For this reason it cannot represent anything specific. This means that to do something useful we should pass around data “objects” through them.
A bean is an object only from a technological point of view. But at the conceptual level it’s just a namespace for procedures. In other words it’s a bunch of procedure grouped by a name. Nothing more. Every bean, regardless the stereotype, is bad.
This is not OOP. But I’m not saying anything new. It’s known that singleton are bad. But this (anti)pattern is the Spring backbone.
At this point it should suffice to say that everything else in Spring is based on bean. This means that every Spring application is composed by bean that works on data structure. Definitely this is not OOP.
However I think that things gets worse with the next two components…

Implement searching and pagination in a Spring Boot application using MongoTemplate
MongoTemplate class provides us features for interacting with the database and offers operations to create, update, delete, and query MongoDB documents in a thread-safe way. The
MongoTemplate class implements the interface
MongoOperations . You can find methods like
MongoOperations has fluent APIs for
Criteria which we will use in this example.
